Fig. 1 is a diagram showing a railway vehicle 1 to which alighting system 100 according to this embodiment is applied.Fig. 2 is a diagram showing alighting apparatus 10 of the railway vehicle 1 in an enlarged state and is a perspective view of thelighting apparatus 10. It should be noted that a configuration of thelighting system 100 is not limited to the following description. - The
lighting system 100 according to this embodiment includes thelighting apparatus 10 and a control apparatus 20 (seeFig. 3 ). Thelighting apparatus 10 is mounted on a first carriage in front in a travelling direction of the railway vehicle 1. Further, thelighting apparatus 10 is covered with a cover (not shown in the figure) for the purpose of enhancing the durability against external shocks, for example. - The
lighting apparatus 10 includesmarker lamps 11, adisplay unit 12,auxiliary lights 13, and alaser illumination 14 as shown inFigs. 1 and2 . Those are provided in the railway vehicle 1 to constitute an identical line over a front surface portion T1 of a first carriage T and both side surface portions T2 and both curved surface portions T3 which are bilaterally symmetric with respect to the front surface portion T1. Themarker lamps 11, theauxiliary lights 13, andsecond display units 12b to be described later thus have configurations bilaterally symmetric with respect to the front surface portion T1. - The
marker lamps 11 according to this embodiment include a plurality oflight sources 11a. The plurality oflight sources 11a is configured to be capable of emitting illumination light forward in the travelling direction of the railway vehicle 1 and is a front marker lamp (head light) of the railway vehicle 1. - The plurality of
light sources 11a is arranged at constant pitch intervals between afirst display unit 12a to be described later and theauxiliary lights 13 such that the optical axes of therespective light sources 11a are parallel to the travelling direction of the railway vehicle 1 while the plurality oflight sources 11a conforms to the curved surface portions T3 between the front surface portion T1 and the side surface portions T2 of the first carriage T. - Further, the plurality of
light sources 11a is respectively arranged within cells C divided by L-shaped partition plates B as shown inFig. 2 . The partition plates B may be made of a material having light reflectance for the purpose of improving the directivity of light emitted by thelight sources 11a, for example. - The
light sources 11a according to this embodiment can be light emitting diode (LED) light sources, for example. In this case, the type of the LED light sources is not particularly limited. For example, a lead frame type, a FLUX type, a surface mount type (SMD), a COB type, or the like may be employed. - The number of
light sources 11a provided in the railway vehicle 1 is not particularly limited and may be one or more. The number oflight sources 11a according to this embodiment is 20 and tenlight sources 11a are provided in each of both the curved surface portions T3 of the railway vehicle 1. The color of illumination light emitted by thelight sources 11a is also not particularly limited. The color of illumination light emitted by thelight sources 11a is typically white. Alternatively, the color of illumination light emitted by thelight sources 11a is determined as appropriate depending on specifications and purposes of thelighting apparatus 10. For example, the color of illumination light emitted by thelight sources 11a may be yellow, green, blue, red, pink, orange, or the like. It should be noted that the curved surface portions T3 in which themarker lamps 11 are arranged may be flat portions. In a case where themarker lamps 11 are used as a rear marker lamp (tail lamp), thelight sources 11a typically emit red illumination light. - The
display unit 12 is constituted by thefirst display unit 12a and thesecond display units 12b. Thefirst display unit 12a is disposed on the front surface (front surface portion T1) in the travelling direction of the railway vehicle 1 between onemarker lamps 11 and theother marker lamps 11 mounted on the first carriage T. Thefirst display unit 12a has an image display screen as a front surface and is configured to be capable of displaying color information, moving images (animation), still images, character information, and the like. - The
first display unit 12a is typically an LED display, though not limited thereto. Any type of display such as a liquid-crystal display and an organic EL display can be employed. - The
second display units 12b are disposed on the curved surface portions T3 between theauxiliary lights 13 and the side surface portions T2, conforming to the curved surface portions T3. Each of thesecond display units 12b has an image display screen as a front surface as in thefirst display unit 12a and is configured to be capable of displaying color information, moving images (animation), still images, character information, and the like. - The
second display unit 12b is typically an LED display, though not limited thereto. Any type of display such as a liquid-crystal display and an organic EL display can be employed. - Each of the
auxiliary lights 13 is disposed on the curved surface portion T3 between themarker lamps 11 and thesecond display unit 12b and are configured to be capable of emitting illumination light. Theauxiliary light 13 is a stop position illumination that functions as an indication when the railway vehicle 1 stops at a station, for example. - The
auxiliary light 13 can be an LED light source, for example. In this case, the LED light source of the above-mentioned type can be employed. The color of illumination light emitted by theauxiliary light 13 is not particularly limited. The color of illumination light emitted by theauxiliary light 13 is determined as appropriate depending on specifications and purposes of thelighting apparatus 10. The color of illumination light emitted by theauxiliary light 13 may be white, yellow, green, blue, red, pink, orange, or the like, for example. - The
laser illumination 14 is substantially continuously provided in the entire periphery (entire lateral surface) of the railway vehicle 1 vertically below themarker lamps 11, thedisplay unit 12, and theauxiliary lights 13, as shown inFig. 1 , and is configured to be capable of emitting illumination light. - The
laser illumination 14 according to this embodiment is configured as a laser illumination that radiates laser light having various wavelengths, which is a laser illumination with a plurality of optical fibers packaged in a tubular shape. - The type of optical fibers that constitute the
laser illumination 14 is not particularly limited. For example, any type of optical fibers such as multimode fibers, single-mode fibers, double cladding fibers, and photonic crystal fibers can be employed. - Further, the color of illumination light emitted by the
laser illumination 14 is also not particularly limited. The color of illumination light emitted by thelaser illumination 14 is determined as appropriate depending on specifications and purposes of thelighting apparatus 10. For example, the color of illumination light emitted by thelaser illumination 14 may be white, yellow, green, blue, red, pink, orange, or the like. -
Fig. 3 is a block diagram showing a configuration example of thelighting system 100. Thecontrol apparatus 20 includes acontroller 21 and alighting circuit 22 as shown in the figure. - The
controller 21 includes hardware required for a computer, such as a central processing unit (CPU), a read only memory (ROM), a random access memory (RAM), and a hard disk drive (HDD). The CPU causes thelighting apparatus 10 to execute lighting patterns based on first and second control modes to be described later by loading a program stored in the ROM or HDD into the RAM and executing the loaded program. - The program is installed in the
control apparatus 20 via various storage media (internal memories), for example. Alternatively, the program may be installed via the Internet or the like. In this embodiment, a microcomputer or the like, for example, is used as thecontrol apparatus 20. Alternatively, any other computer may be used. - The
controller 21 according to this embodiment controls thelighting apparatus 10 on the basis of an output of adetector 30 configured to be capable of detecting a travelling state of the railway vehicle 1. With this configuration, depending on the travelling state of the railway vehicle 1, thecontroller 21 causes some or all of the plurality oflight sources 11a to light up on the first control mode and causes the plurality oflight sources 11a and thedisplay unit 12 to light up on the second control mode, as will be described later. - In this case, the
controller 21 executes control on thelaser illumination 14 on the basis of an output of thedetector 30, for example, to change the line color of the railway vehicle 1 in a manner that depends on the travelling state of the vehicle. It should be noted that thecontroller 21 is not limited to the output of thedetector 30 and is also capable of controlling thelighting apparatus 10 on the basis of traffic data in which the travelling state of the railway vehicle 1 is recorded. - The
detector 30 is provided in the railway vehicle 1 and is connected to controlapparatus 20 wirelessly or wired. Thedetector 30 is a monitoring sensor configured to be capable of detecting the travelling state of the railway vehicle 1 (travelling, stop, entering the station, or the like), the amount of movement (travelling distance or the like), and the like, for example. - In this embodiment, a wheel speed sensor capable of detecting the r.p.m. or the like of the wheels of the railway vehicle 1, a speed sensor capable of detecting the speed of the railway vehicle 1, or the like can be employed as the monitoring sensor, though not limited thereto.
- For example, the monitoring sensor may be a global positioning system (GPS) sensor capable of detecting a current location of the railway vehicle 1 with radio waves from an artificial satellite, an open/close sensor capable of detecting open/close of doors of the railway vehicle 1, or the like.
- In addition, the
controller 21 is also capable of controlling thelighting apparatus 10 on the basis of an output of aninput unit 40 for inputting a user's operation. This configuration causes thelighting apparatus 10 to execute a lighting pattern desired by the user. An operation device such as a touch panel and a keyboard, for example, is employed as theinput unit 40. - The
lighting circuit 22 is constituted by a switching element that switches lighting/extinguishing of thelighting apparatus 10 and the like. Thelighting circuit 22 switches ON/OFF of a switching element corresponding to each of themarker lamps 11, thedisplay unit 12, theauxiliary lights 13, and thelaser illumination 14 in accordance with a control signal output by thecontroller 21. With this configuration, lighting/extinguishing of each of themarker lamps 11, thedisplay unit 12, theauxiliary lights 13, and thelaser illumination 14 is controlled. - Next, a control method of the
control apparatus 20 will be described.Fig. 4 is a flowchart showing a method in which thecontrol apparatus 20 controls thelighting apparatus 10. - The
control apparatus 20 according to this embodiment performs control to switch, in accordance with the travelling state of the railway vehicle 1, the first control mode on which lighting control intended for themarker lamps 11 of the railway vehicle 1 is executed and the second control mode on which lighting control intended for themarker lamps 11 and thedisplay unit 12 is executed. - First of all, the
detector 30 monitors whether or not the railway vehicle 1 is travelling (S01). Subsequently, in a case where thedetector 30 detects a travelling state of the railway vehicle 1 (YES in S01), whether or not the railway vehicle 1 has entered the station is monitored (S02). At this time, thecontroller 21 determines whether or not the railway vehicle 1 is in the travelling state on the basis of an output of thedetector 30 which is obtained by detecting the speed of the railway vehicle 1, the r.p.m. of the wheels, or the like, for example. - Subsequently, in a case where the
detector 30 has not detected that the railway vehicle 1 has entered the station (NO in S02), the first control mode is executed (S03).Figs. 5 and 6 are schematic views in which thelighting apparatus 10 is simplified and are diagrams each showing the lighting pattern based on the first control mode. - In this embodiment, all the plurality of
light sources 11a and thelaser illumination 14 light up in white and theauxiliary light 13 is extinguished as the first control mode (seeFig. 5 ). With this operation, a high beam is configured. That is, illumination light is emitted forward in the travelling direction of the railway vehicle 1 at a high output. A head light function of the railway vehicle 1 is realized. It should be noted that in Application Example 1, arbitrary information such as a moving image, color information, and character information may be displayed on thedisplay unit 12. - Further, on the first control mode, only four of the
light sources 11a, which are closer to theauxiliary light 13, and thelaser illumination 14 may light up in white and thedisplay unit 12 and theauxiliary light 13 may be extinguished (seeFig. 6 ). With this operation, a low beam is configured. That is, the output of the illumination light is lower than the above-mentioned high beam or the optical axis is changed. - It should be noted that on the first control mode, the color of illumination light of the
auxiliary light 13 and thelaser illumination 14 is not limited to the above-mentioned color as a matter of course. Further, the black shown inFigs. 5 and 6 indicates white lighting and the same applies to the following figures. - First of all, the
detector 30 monitors whether or not the railway vehicle 1 is travelling (S01). Subsequently, in a case where thedetector 30 has detected the travelling state of the railway vehicle 1 (YES in S01), whether or not the railway vehicle 1 has entered the station is monitored (S02). - Subsequently, in a case where the
detector 30 has detected that the railway vehicle 1 has entered the station (YES in S02), a first lighting pattern based on the second control mode is executed (S04). At this time, thecontroller 21 determines whether or not the railway vehicle 1 has entered the station on the basis of an output of thedetector 30, the output being obtained by detecting that the railway vehicle 1 has decelerated to a predetermined speed and has travelled by a predetermined distance (travelling distance from the station), for example. -
Fig. 7 is a schematic view in which thelighting apparatus 10 is simplified and is a diagram showing the first lighting pattern. In this embodiment, some of the plurality oflight sources 11a are caused to light up and the other light sources are caused to blink as the first lighting pattern. - Specifically, only four of the
light sources 11a, which are closer to theauxiliary light 13, light up in white and white blinking is repeated to the sixthlight source 11a numbered from a side closer to thefirst display unit 12a so as to sequentially flow toward the sixthlight source 11a from thefirst display unit 12a (seeFig. 7 ). - At this time, light-emitting imitating the light-emitting mode of the
light sources 11a is executed on thefirst display unit 12a and the character information, for example, is displayed on thesecond display unit 12b. Further, theauxiliary light 13 switches from green blinking to lighting and thelaser illumination 14 blinks in blue. It should be noted that the character information displayed on thefirst display unit 12a shown inFig. 7 is an example and the present invention is not limited to this character information. - By causing the
lighting apparatus 10 to apply the first lighting pattern, both of the head light function of themarker lamps 11 and a function of presentation excellent in decorativeness can be achieved when the railway vehicle 1 enters the station. It should be noted that in the first lighting pattern, the color of illumination light of thelight sources 11a, thefirst display unit 12a, theauxiliary lights 13, and thelaser illumination 14 is not limited to the above-mentioned color as a matter of course. - First of all, the
detector 30 monitors whether or not the railway vehicle 1 is travelling (S01). Subsequently, in a case where thedetector 30 has not detected that the railway vehicle 1 is travelling (NO in S01), whether or not the railway vehicle is in an emergency situation is determined (S07). Details of the emergency mode will be described later. - Subsequently, in a case where the railway vehicle 1 determines that the railway vehicle is not in the emergency situation (NO in S07), a second lighting pattern based on the stop of the railway vehicle 1 is executed as the second control mode (S05). At this time, the
controller 21 determines whether or not the railway vehicle 1 has stopped at the station on the basis of an output of thedetector 30, the output being obtained by detecting that rotation of the wheels of the railway vehicle 1 has stopped or the doors have been opened, for example. -
Figs. 8 and9 are schematic views in which thelighting apparatus 10 is simplified and are diagrams each showing the second lighting pattern. In this embodiment, the plurality oflight sources 11a is caused to blink and first andsecond display units - Specifically, in all of the plurality of
light sources 11a, white blinking which moves toward the auxiliary light 13 from the side closer to thefirst display unit 12a and moves back to the side closer to thefirst display unit 12a is repeated so as to sequentially flow (seeFig. 8 ). At this time, theauxiliary light 13 is extinguished and thelaser illumination 14 blinks in blue. In this case, color information whose color is changed in the order of green, blue, orange, and white may be displayed on the first andsecond display units laser illumination 14 gradually changes in the above-mentioned order may be executed. - Alternatively, in all of the plurality of
light sources 11a, the light-emitting mode on which white blinking which moves toward the auxiliary light 13 from the side closer to thefirst display unit 12a and moves back to the side closer to thefirst display unit 12a is repeated so as to sequentially flow and the light-emitting mode on which red blinking which moves toward thefirst display unit 12a from a side closer toauxiliary light 13 and moves back to the side closer to theauxiliary light 13 is repeated so as to sequentially flow may be concurrently performed (seeFig. 9 ). At this time, the first andsecond display units auxiliary light 13 are extinguished and thelaser illumination 14 lights up in pink. - Alternatively, pink lighting/blinking in which all of the plurality of
light sources 11a and the first andsecond display units light sources 11a may light up in pink and moving images may be displayed on the first andsecond display units laser illumination 14 lights up in pink and then is gradually extinguished (so-called fade out control) and theauxiliary light 13 is extinguished. - By applying the second lighting pattern to the
lighting apparatus 10, for example, the railway vehicle 1 which has stopped at the station can be made to have a function of presentation more excellent in decorativeness and entertainment properties for vehicle users outside the vehicle can be improved. - First of all, the
detector 30 monitors whether or not the railway vehicle 1 is travelling (S01). Subsequently, in a case where thedetector 30 has not detected that the railway vehicle 1 is travelling (NO in S01), whether or not the railway vehicle 1 is in the emergency situation is determined (S07). - At this time, the
controller 30 determines that the railway vehicle 1 is in the emergency situation on the basis of an input made by a member of a crew via theinput unit 40 in a case where the railway vehicle 1 has stopped due to a malfunction, for example. - Subsequently, in a case where it is determined that the railway vehicle 1 is in the emergency situation (YES in S07), a light-emitting pattern similar to an abnormal lighting pattern to be described later is executed as the emergency mode (see
